Reasonable on 15 August 2008
I don't have clue but think a lot will be down to how the Japanese react to the art style and approach. If they like it then it could actually sell like gangbusters... and I can see the Japanese getting a lick out of creating and sharing levels with friends... but on the other hand they could just ignore it from the get go.
What's funny about LBP is its really a small game, build by a small studio who themselves seem to have refrained from hyping the title, that has turned into something potentially big for the PS3 and has Sony really pushing the title.
I sometimes get the feeling the actual developers would prefer less hype than they're getting but I suppose its out of their hands now.
Try to be reasonable... its easier than you think...
